Cov yam ntxwv ntawm lub tsev Additives

Cov yam ntxwv ntawm lub tsev additives yog txawv, feem ntau nrog rau hmoov, granular, fibrous thiab lwm yam ntaub ntawv. Cov khoom siv hauv tsev xws li cov dej txo qis, cov tshuaj tiv thaiv dej, cov thickeners, thiab lwm yam, muaj cov yam ntxwv hauv qab no:

Dej reducer: feem ntau yog dawb los yog lub teeb daj hmoov los yog granules.
Waterproofing tus neeg saib xyuas: tuaj yeem yog lub teeb daj hmoov lossis cov kua pob tshab.
Thickener: feem ntau yog cov hmoov dawb los yog cov kua pob tshab.
Polymer cov ntaub ntawv hauv tsev: dawb fibrous lossis granular hmoov.
Tsis tas li ntawd, cov khoom siv hauv tsev ua lub luag haujlwm tseem ceeb hauv cov khoom siv hauv tsev thiab tuaj yeem txhim kho kev ua haujlwm ntawm cov ntaub ntawv. Piv txwv li:

Dej reducer: txo cov dej - cement piv hauv cov cement pob zeb, txhim kho lub zog thiab kav ntev ntawm cov pob zeb, thiab txo qhov shrinkage thiab tawg.
Waterproofing tus neeg saib xyuas: txhim kho cov dej tsis zoo ntawm cov khoom siv hauv tsev thiab tiv thaiv dej nkag mus zoo.
Thickener : siv los ua kom cov viscosity thiab viscosity ntawm cov kua, feem ntau siv hauv tshuaj pleev ib ce, txheej, inks thiab lwm yam khoom.
